Militant and political group Hamas on Saturday blamed Israel for the alleged assassination of one of its members in Malaysia on his way to a mosque for prayers.

Hamas said 35-year-old Fadi al-Batsh was killed at dawn in the Malaysian capital of Kuala Lumpur. Hamas officials didn’t disclose Mr. al-Batsh’s role in the Islamist movement or how he was assassinated but said he was a researcher in “the field of energy.”
